When I upgraded my site from 2.4.4 to 2.5.1 there was no upgrade folder in 2.5.1 so I used the upgrade folder from 2.5.0
Everything went nice and smooth. But afterwards I noticed little things in the admin not working right. Not sure why I looked, but in the mainfile.php I noticed all my database info was there. I thought to myself that should not be there, it should be in secure.php.
I FORGOT to make the mainfile.php writable. The Upgrade SHOULD have noticed that and warned me, I would think. But it did not, it went right through the upgrade process. So I had to create secure.php by hand and also recreate mainfile.php manually.
It happened to two sites before I caught it.
Just thought I should let someone know
Thanks,
John
